Description

Indication information receiving and sending method, communication node and storage medium Technical Field

[0001] The present application relates to the field of wireless communication technology, for example, to a method for receiving and sending indication information, a communication node and a storage medium. Background Art

[0002] In scenarios where a base station sends a perception signal, a user equipment (UE) receives the perception signal for perception, and uses the perception results to assist in communication, there are some issues that affect communication performance. For example, it is difficult to determine the beam for uplink signal transmission and the best serving base station. The optimal timing of the communication signal changes with the movement of the UE and the changes in the channel environment. However, due to the high accuracy requirements of perception, the timing of receiving the perception signal should be fixed at a certain moment, which causes timing offset and increases resource overhead during the signal reception process. In addition, conflicts may occur when receiving the perception signal and the communication signal. How to use the perception signal to improve communication performance has become an urgent problem to be solved.

[0041] The present application is described below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application. It should be noted that, unless there is a conflict, the embodiments and features within the embodiments of the present application may be combined with each other in any manner. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present application, not all structures.

[0042] The indication information receiving method or indication information sending method of the embodiment of the present application mainly utilizes the characteristics of the perception signal to improve communication performance in a scenario where the second communication node (network side node) sends a perception signal and the first communication node (user side node) receives the perception signal for perception and auxiliary communication.

[0043] Figure 1 is a flowchart of a method for receiving indication information according to an embodiment. This method can be applied to a first communication node, which is a receiver of the perception signal indication information and can be a user-side node, such as a UE. As shown in Figure 1 , the method provided in this embodiment includes steps 110 and 120.

[0044] In step 110, perception signal indication information is received, where the perception signal indication information is used to indicate a quasi-co-location relationship between a perception signal and a first signal.

[0045] In step 120, communication is performed with the second communication node according to the perception signal indication information.

[0046] In this embodiment, the first communication node receives a communication signal, and its optimal timing varies with the movement of the first communication node and changes in the channel environment. Generally speaking, the signal reception time offset can be correctly received within a cyclic prefix (CP) range. The first communication node receives a perception signal. Due to the high accuracy requirements of perception, its timing should be fixed at a certain moment. Utilizing this property of the perception signal, the perception signal and the first signal are set to meet a quasi-colocation (QCL) relationship. The first signal can be a communication signal, a reference signal, and / or a signal transmitted by a data port, etc. The signal transmitted by the data port can also be understood as a pilot corresponding to the data port.

[0047] The quasi-co-location relationship can be used to indicate that the properties of the two antenna ports transmitting symbols are relatively close. If the large-scale channel characteristics of the symbols transmitted on one antenna port can be inferred from the channel characteristics of the symbols transmitted on another antenna port, the two antenna ports are called QCL. The large-scale characteristics include one or more delay spread (Delay Spread), Doppler spread (Doppler Spread), Doppler shift (Doppler Shift), average gain (Average Gain), average delay (Average Delay) and spatial receive parameters (Spatial Rx Parameter). The 5G New Radio (NR) can pre-configure a series of QCL relationships through high-layer signaling. Each QCL relationship is identified by a Transmission Configuration Indicator (TCI) state (State). The second communication node can configure the TCI-State for the first communication node through the Radio Resource Control (RRC) high-layer parameters. The first communication node obtains the corresponding TCI indication by demodulating the downlink control information (DCI). Each TCI state can be indexed by TCI-State. The second communication node represents different quasi co-location relationships through different quasi co-location types (QCL-Type).

[0048] By setting the perception signal and the first signal to satisfy the QCL relationship, the problem of timing offset can be solved, and the perception signal can be used to replace the function of the first signal, thereby eliminating the need to transmit the first signal, saving resource overhead, and improving communication performance.

[0049] In one embodiment, the first signal includes a downlink communication signal; the perception signal indication information further includes an offset parameter;

[0050] Communicating with the second communication node according to the perception signal indication information, including:

[0051] receiving a perception signal and a downlink communication signal sent by a second communication node;

[0052] The delay parameter of the downlink communication signal is the sum of the delay parameter and the offset parameter of the perception signal, or the timing parameter of the perception signal is the sum of the timing parameter and the offset parameter of the most recently received downlink communication signal.

[0053] In this embodiment, the first communication node may receive the perception signal and the downlink communication signal based on the QCL relationship indicated by the perception signal indication information. In the synaesthesia integrated system, the second communication node transmits a perception signal to the first communication node, notifying the first communication node that the received downlink communication signal and the perception signal satisfy the QCL relationship. The second communication node then notifies the first communication node of an offset parameter (Offset). The second communication node transmits the downlink communication signal, and the first communication node receives the subsequent downlink communication signal based on the QCL relationship of the previously received perception signal, thereby resolving the timing offset issue and implementing perception-assisted communication.

[0054] Table 1 shows a QCL relationship between a downlink communication signal and a perception signal. As shown in Table 1, the delay parameter of the downlink communication signal is the sum of the delay parameter and the offset parameter of the perception signal.

[0055] Table 1 QCL relationship between downlink communication signal and perception signal

[0056] In one embodiment, the communication process between the first communication node (taking a UE as an example) and the second communication node (taking a base station as an example) includes:

[0057] (1) The base station sends a sensing signal to the UE.

[0058] (2) The UE receives the sensing signal based on the clock configured by RRC and measures the QCL parameters of the sensing signal, such as Doppler shift, Doppler spread, spatial Rx Paremeter, average delay, and delay spread.

[0059] (3) Considering the different timings of the sensing signal and the communication signal, an additional offset parameter Offset needs to be configured. The base station notifies the UE of the offset parameter Offset.

[0060] (4) The base station notifies the UE that the downlink communication signal it receives satisfies the QCL relationship with the perception signal. This means that one or more of the Doppler Shift, Doppler Spread, and Spatial Rx Paremeter parameters of the downlink communication signal and the perception signal are the same, and the delay parameter (Average Delay or Delay Spread) of the downlink communication signal is equal to the sum of the delay parameter (Average Delay or Delay Spread) of the perception signal and the Offset.

[0061] (5) The base station sends a downlink communication signal, which can be one or more of the following: synchronization signal / physical broadcast channel block (Synchronization Signal / PBCH Block, SSB), CSI-RS, demodulation reference signal (DeModulation Reference Signal, DM-RS) (which can be the DM-RS of PDSCH or physical downlink control channel (Physical Downlink Control Channel, PDCCH) or the DM-RS of SSB), and tracking reference signal (Tracking Reference Signal, TRS).

[0062] (6) The UE receives the downlink communication signal according to the QCL relationship based on the sensing signal and the additional bias information, thereby solving the timing offset problem and realizing sensing-assisted communication.

[0063] Table 2 shows another QCL relationship between a downlink communication signal and a perception signal. As shown in Table 2, the timing parameter of the perception signal is the sum of the timing parameter and the offset parameter of the most recently received downlink communication signal.

[0064] Table 2 QCL relationship between downlink communication signal and perception signal

[0065] In one embodiment, the communication process between the first communication node (taking a UE as an example) and the second communication node (taking a base station as an example) includes:

[0066] (1) The base station sends a downlink communication signal, which can be one or more of SSB, CSI-RS, DM-RS (which can be DM-RS of PDSCH or PDCCH, or DM-RS of SSB), and TRS.

[0067] (2) The UE receives the downlink communication signal based on the clock configured by RRC and measures parameters such as doppler shift, Doppler spread, spatial Rx Paremeter, average delay, and delay spread of the downlink communication signal.

[0068] (3) Considering the different timings of downlink communication signals and sensing signals, an additional offset parameter Offset needs to be configured. The base station notifies the UE of the offset parameter Offset.

[0069] (4) The base station notifies the UE that the received downlink communication signal and the perception signal satisfy the QCL relationship. That is, the downlink communication signal and the perception signal have the same one or more of the Doppler Shift, Doppler Spread, and Spatial Rx Paremeter parameters, and the timing parameters of the perception signal are equal to the sum of the timing parameters of the most recently received downlink communication signal and the offset.

[0070] (5) The UE receives the sensing signal based on the QCL relationship of the downlink communication signal and additional bias information, thereby solving the timing offset problem.

[0071] In one embodiment, the first signal includes a reference signal for setting a direction; the set direction is uplink or downlink; the reference signal includes a Phase Tracking Reference Signal (PTRS), a Sounding Reference Signal (SRS) and / or a Channel State Information Reference Signal (CSI-RS);

[0072] Communicating with the second communication node according to the perception signal indication information includes: transmitting a perception signal of a set direction to the second communication node according to the perception signal indication information, and not transmitting a reference signal of the set direction.

[0073] In this embodiment, the reference signal in the set direction and the perception signal satisfy the QCL relationship, and the reference signal in the set direction includes downlink PTRS, downlink CSI-RS, uplink PTRS and / or uplink SRS, etc. In the synaesthesia integrated system, the second communication node transmits a perception signal to the first communication node, notifying the first communication node that the reference signal in the set direction (uplink or downlink) and the perception signal in the set direction satisfy the QCL relationship, so that the reference signal in the set direction can be omitted and the perception signal in the set direction can be used to replace the reference signal in the corresponding direction, thereby realizing perception-assisted communication and saving communication resource overhead.

[0074] In one embodiment, the communication process between the first communication node (taking a UE as an example) and the second communication node (taking a base station as an example) includes:

[0075] Mode 1: The downlink sensing signal replaces the downlink reference signal function:

[0076] (1) The base station notifies the UE that the downlink PTRS and / or downlink CSI-RS and the downlink sensing signal meet the QCL relationship.

[0077] (2) The base station sends a downlink sensing signal to the UE.

[0078] (3) The UE does not receive the downlink reference signal, but directly uses the received downlink sensing signal to perform downlink PTRS and / or downlink CSI-RS functions.

[0079] Mode 2: Uplink sensing signal replaces uplink reference signal function:

[0080] (1) The base station notifies the UE that the uplink PTRS and / or uplink SRS and the uplink sensing signal satisfy the QCL relationship.

[0081] (2) UE sends uplink perception signal;

[0082] (3) Within a certain time threshold, the uplink sensing signal is used to replace the uplink reference signal, and no additional uplink PTRS and / or uplink SRS reference signals are sent.

[0083] In one embodiment, the first signal corresponds to a physical shared channel of a set direction of at least one port; the set direction is uplink or downlink;

[0084] Communicating with the second communication node according to the perception signal indication information, including:

[0085] The perception signal of the set direction is transmitted to the second communication node according to the perception signal indication information, and the pilot corresponding to the physical shared channel of the set direction of at least one port is not transmitted.

[0086] In this embodiment, the physical shared channel of the set direction and the perception signal of the set direction satisfy the QCL relationship. The physical shared channel of the set direction can be an uplink physical shared channel (Physical Uplink Shared Channel, PUSCH) or a downlink physical shared channel (Physical Downlink Shared Channel, PDSCH). Take the following behavior as an example. In the integrated communication system, the second communication node transmits a downlink perception signal to the first communication node. The second communication node notifies the first communication node that the port PDSCH and the downlink perception signal satisfy the QCL relationship. The channel response of the PDSCH is the same as the channel response of the perception signal, so that the pilot corresponding to the PDSCH can be omitted. The downlink perception signal sent by the second communication node replaces the pilot function of a certain port / ports of the PDSCH, thereby realizing perception-assisted communication and saving communication resource overhead.

[0087] In one embodiment, the quasi-co-location relationship includes at least one of the following:

[0088] a QCL relationship between a physical shared channel port in a set direction and a sensing signal in a set direction;

[0089] a QCL relationship between one of the plurality of physical shared channel ports of the set direction and a sensing signal of the set direction;

[0090] QCL relationship between N data ports and M sensing signals of set directions.

[0091] In one embodiment, the quasi-co-location relationship includes a QCL relationship between N data ports and M sensing signals of a set direction; the method further includes:

[0092] In the case of M>N, the receiving sensing signal port vacancy information;

[0093] In the case of M<N, the data port vacancy information is received.

[0094] In one embodiment, taking the case where the direction is set to downlink as an example, the first communication node is a UE, and the second communication node is a base station, the quasi-co-location relationship includes at least one of the following:

[0095] Mode 1: A PDSCH port and a downlink sensing signal meet the QCL relationship:

[0096] (1) The base station notifies the UE that the PDSCH and the downlink sensing signal satisfy the QCL relationship.

[0097] (2) The base station sends a downlink sensing signal, and the UE receives the sensing signal and measures the channel response of the sensing signal.

[0098] (3) The base station sends PDSCH at one antenna port, and the channel response of the PDSCH at this port is the same as the channel response of the downlink sensing signal.

[0099] (4) At this time, the pilot corresponding to the PDSCH may not be sent, and the downlink sensing signal may be used to replace the function of the PDSCH pilot.

[0100] Mode 2: One of the multiple PDSCH ports and a downlink sensing signal meet the QCL relationship:

[0102] (2) The base station sends a downlink sensing signal, and the UE receives the sensing signal and measures the channel response of the sensing signal.

[0103] (3) The base station uses multiple antenna ports to send PDSCH, and the channel response of the PDSCH on one port is the same as the channel response of the downlink sensing signal.

[0104] (4) The PDSCH pilot corresponding to the port may not be sent, and the downlink sensing signal may be used to replace the function of the PDSCH pilot of the port.

[0105] Mode 3: There is a QCL relationship between N data ports and M downlink sensing signals:

[0106] (1) The base station notifies the UE that there is a QCL relationship between the PDSCHs of the N data ports and the M downlink sensing signals, and leaves the redundant ports vacant. Specifically:

[0107] When M<N, the base station needs to notify the UE of the one-to-one correspondence between the M downlink sensing signals and the M data port PDSCHs, as well as the vacancy status of the (NM) data ports.

[0108] When M=N, the base station only needs to notify the UE of the one-to-one correspondence between the M downlink sensing signals and the N data port PDSCHs.

[0109] When M>N, the base station needs to notify the UE of the one-to-one correspondence between N downlink sensing signals and N data ports PDSCH, as well as the vacancy status of (MN) sensing signal ports.

[0110] (2) The base station sends M downlink sensing signals simultaneously.

[0111] (3) The base station uses multiple data ports to send PDSCH. According to the specific situation in (1), the channel response of the PDSCH sent by some data ports is the same as the channel response of some downlink sensing signals, and they correspond one to one.

[0112] (4) The PDSCH pilot corresponding to the above port may not be sent, and the downlink sensing signal may be used to replace the function of the PDSCH pilot.

[0113] In one embodiment, taking the above behavior as an example, in the integrated synaesthesia system, the second communication node notifies the first communication node that the port PUSCH and the uplink perception signal satisfy the QCL relationship, and the channel response of the PUSCH is the same as the channel response of the uplink perception signal, so that the pilot corresponding to the PUSCH can be not sent, and the uplink perception signal sent by the first communication node is used to replace the pilot function of a certain port / ports of the PUSCH, thereby realizing perception-assisted communication and saving communication resource overhead.

[0114] Taking the case where the direction is set to downlink as an example, the first communication node is a UE, and the second communication node is a base station. The quasi co-location relationship includes at least one of the following ways:

[0115] Method 1: One PUSCH port and one uplink sensing signal meet the QCL relationship

[0116] (1) The base station notifies the UE that the PUSCH and the uplink sensing signal satisfy the QCL relationship.

[0117] (2) The UE sends an uplink perception signal.

[0118] (3) The UE sends a PUSCH. The channel response of the PUSCH sent by this port is the same as the channel response of the sensing signal.

[0119] (4) At this time, the pilot corresponding to the PUSCH may not be sent, and the uplink sensing signal can be used to replace the function of the PUSCH pilot.

[0120] Method 2: One of multiple PUSCH ports and an uplink sensing signal meet the QCL relationship

[0121] (1) The base station notifies the UE that the PUSCH of a certain port and the uplink sensing signal meet the QCL relationship.

[0122] (2) The UE sends an uplink perception signal.

[0123] (3) The UE uses multiple antenna ports to send PUSCH, and the channel response of the PUSCH sent by one port is the same as the channel response of the sensing signal.

[0124] (4) The corresponding pilot of the PUSCH corresponding to the port may not be sent, and the uplink sensing signal is used to replace the function of the PUSCH pilot of the port.

[0125] Method 3: There is a QCL relationship between N data ports and M uplink sensing signals

[0126] (1) The base station notifies the UE that there is a QCL relationship between the PUSCHs of the N data ports and the M uplink sensing signals, and leaves the redundant ports vacant. Specifically:

[0127] When M<N, the base station needs to notify the UE of the one-to-one correspondence between the M uplink sensing signals and the M data ports PUSCH, as well as the vacancy status of the (NM) data ports.

[0128] When M=N, the base station only needs to notify the UE of the one-to-one correspondence between the M uplink sensing signals and the N data ports PUSCH.

[0129] When M>N, the base station needs to notify the UE of the one-to-one correspondence between N uplink sensing signals and N data ports PUSCH, as well as the vacancy status of (MN) sensing signal ports.

[0130] (2) The UE sends M uplink sensing signals simultaneously.

[0131] (3) The UE uses multiple data ports to send PUSCH. According to the specific situation in (1), the channel response of the PUSCH sent by some data ports is the same as the channel response of some uplink sensing signals, and they correspond one to one.

[0132] (4) The PUSCH pilot corresponding to the above port may not be sent, and the uplink sensing signal may be used to replace the PUSCH pilot function.

[0133] Figure 2 is a flowchart of a method for receiving indication information according to an embodiment. This method can be applied to a first communication node, which is a receiver of the perception signal indication information and can be a user-side node, such as a UE. As shown in Figure 2, the method provided in this embodiment includes steps 210 and 220.

[0134] In step 210, perception signal indication information is received, where the perception signal indication information is used to indicate that a perception signal is used as an associated pilot of a second signal.

[0135] In step 220, the second signal is sent according to the perception signal indication information.

[0136] The Reference Signal (RS), also known as a pilot signal, is a known signal provided by the transmitter to the receiver for channel estimation or channel sounding. The CSI-RS can be used for downlink channel measurement, obtaining downlink channel state information, beam management, mobility management, and rate matching. The DM-RS is used for uplink or downlink channel estimation to demodulate the corresponding physical channels, such as the PDSCH, PDSCH, PDCCH, or PUCCH. The PTRS can be used for uplink or downlink phase noise tracking and compensation. The SRS can be used for uplink channel measurement, time-frequency synchronization, and beam management.

[0137] In this embodiment, the associated pilot can be used to implement beam management and achieve perception-assisted communication. The perception signal is used as the associated pilot of the UE uplink signal. The UE can use the associated pilot to determine the beam to send the uplink signal and the best serving base station.

[0138] In one embodiment, the second signal includes an uplink signal;

[0139] The sending the second signal according to the perception signal indication information includes:

[0140] determining a transmission beam direction of the second signal according to the associated pilot;

[0141] The second signal is transmitted according to the transmission beam direction.

[0142] In this embodiment, the sensing-assisted communication can be used for beam management. The sensing signal is used as an associated pilot for the uplink signal of the first communication node. The first communication node can use the associated pilot to determine the beam to send the uplink signal and the best serving base station.

[0143] In one embodiment, the first communication node is a UE, and the second communication node is a base station. The UE can use the sensing signal to determine the optimal uplink signal transmission direction. The base station notifies the UE to use a sensing signal as an associated pilot for the UE's uplink signal. The UE then determines the beam to transmit the uplink signal based on the associated pilot, thus implementing sensing-assisted communication.

[0144] FIG3 is a schematic diagram of a perception-assisted communication system provided by an embodiment. As shown in FIG3 , the communication process between the base station and the UE includes:

[0145] (1) The gNB notifies the UE to use a certain sensing signal as the associated pilot of the UE uplink signal.

[0146] (2) Determine the uplink signal transmission beam direction based on the associated pilot direction corresponding to the optimal communication base station and perform subsequent communication functions.

[0147] In one embodiment, the number of the sensing signals is at least two;

[0148] The method further comprises:

[0149] determining a target-associated pilot based on at least two sensing signals;

[0150] A second communication node is determined based on the target associated pilot.

[0151] In this embodiment, the second communication node can use the sensing signal to assist in selecting the optimal first communication node. Figure 4 is a schematic diagram of another sensing-assisted communication system provided by one embodiment. The first communication node is a UE, and the second communication node is a base station. As shown in Figure 4, there are two base stations and one UE in the system. gNB1 notifies the UE to use sensing signal 1 as the associated pilot of the UE uplink signal, and gNB2 notifies the UE to use sensing signal 2 as the associated pilot of the UE uplink signal. The UE further compares the associated pilots of the two base stations, determines the base station corresponding to the better associated pilot as the serving base station, and determines the uplink signal transmission direction based on the best associated pilot direction corresponding to the serving base station. The UE determines the relative positions of multiple nearby base stations based on the associated pilots, and selects the optimal communication base station for subsequent information exchange, which helps to reasonably adjust the CSI measurement and feedback frequency and assist the base station in reasonable energy saving.

[0152] The communication process between the base station and the UE includes:

[0153] (1) gNB1 notifies the UE to use sensing signal 1 as the associated pilot of the UE uplink signal.

[0154] (2) gNB2 notifies the UE to use sensing signal 2 as the associated pilot of the UE uplink signal.

[0155] (3) The UE compares the associated pilots in the directions k1 and k2, and selects the base station corresponding to the better associated pilot as the serving base station (in Figure 4, the k2 direction is selected as an example) to perform subsequent communication functions.

[0156] (4) Determine the uplink signal transmission beam direction based on the associated pilot direction corresponding to the optimal communication base station.

[0157] Figure 5 is a flowchart of a method for receiving indication information according to an embodiment. This method can be applied to a first communication node, which is a receiver of the perception signal indication information and can be a user-side node, such as a UE. As shown in Figure 5 , the method provided in this embodiment includes steps 310 and 320.

[0158] In step 310, perception signal indication information is received, where the perception signal indication information includes priority information of at least one of a perception signal and a communication signal.

[0159] In step 320, a perception signal and a communication signal are received according to the perception signal indication information.

[0160] In this embodiment, taking into account the timing difference between the communication signal and the perception signal, a conflict may occur when the first communication node receives the perception signal and the communication signal. The perception signal indication information is used to indicate the priority of the perception signal and / or the priority of the communication signal. The first communication node can make a decision on whether to prioritize receiving the perception signal or the perception signal, thereby avoiding or resolving conflicts that may occur when multiple signals arrive at the receiving end at the same time.

[0161] In one embodiment, the priority information includes: a priority of the perception signal being lower than a priority of the communication signal;

[0162] Receiving a perception signal and a communication signal according to the perception signal indication information, including:

[0163] According to the perception signal indication information, if the perception signal arrives first and the communication signal arrives before the perception signal is completely received, the reception of the perception signal is interrupted and the communication signal is received first. After the communication signal is completely received, the next perception signal with a complete cycle starting with the optimal timing is waited for to arrive and the perception signal is received again.

[0164] According to the perception signal indication information, if the communication signal arrives first and the perception signal arrives before the communication signal is completely received, after the communication signal is completely received, wait for the next perception signal of a complete cycle starting with the optimal timing to arrive and re-receive the perception signal;

[0165] According to the perception signal indication information, when the perception signal and the communication signal arrive at the same time, the communication signal is received. After the communication signal is received, the next perception signal of a complete cycle starting with the optimal timing is waited for to arrive and the perception signal is received again.

[0166] In this embodiment, the periodicity of the perception signal can be utilized to determine that the priority of the perception signal is lower than the priority of the communication signal. Figure 6 is a schematic diagram of a method for preferentially receiving a communication signal, provided in one embodiment. As shown in Figure 6, generally, considering that the communication signal is only transmitted once, the perception signal is typically transmitted multiple times periodically. The first communication node (using the UE as an example) can preferentially receive the communication signal and then start receiving the perception signal from the next period.

[0167] The first communication node preferentially receives the communication signal, specifically in the following situations:

[0168] (1) If the perception signal arrives at the UE first, and the communication signal arrives at the UE before the perception signal is completely received, the UE can interrupt the reception of the perception signal and give priority to receiving the communication signal, considering the periodic transmission characteristics of the perception signal. After the communication signal is completely received, the UE waits for the arrival of the next perception signal with a complete cycle starting with the optimal timing and then starts receiving it again.

[0169] (2) If the communication signal arrives at the UE first, and the perception signal arrives at the UE before the communication signal is fully received, the UE continues to receive the communication signal until it is fully received. The UE then waits for the next perception signal with a complete cycle starting with the optimal timing to arrive and then receives it again.

[0170] (3) If the perception signal and the communication signal arrive at the UE at the same time, the UE directly chooses to receive the communication signal. After the communication signal is received, the UE waits for the next full cycle of the perception signal starting with the optimal timing to arrive and then receives it again.

[0171] In one embodiment, the priority information includes: a priority identifier;

[0172] Receiving a perception signal and a communication signal according to the perception signal indication information, including:

[0173] In the case where both the communication signal and the perception signal carry a priority identifier, or in the case where neither the communication signal nor the perception signal carries a priority identifier, the communication signal is received first, and after the communication signal is received, the next full cycle of the perception signal starting with the best timing is waited for to arrive and the perception signal is received again;

[0174] If the communication signal arrives first and the perception signal arrives before the communication signal is fully received, and the perception signal carries a priority identifier, interrupting reception of the communication signal, giving priority to receiving the perception signal, requesting retransmission of the communication signal, and receiving the retransmitted communication signal;

[0175] In the event that the communication signal arrives first and the perception signal arrives before the communication signal is completely received, and the communication signal carries a priority identifier, the communication signal is received. After the communication signal is completely received, the perception signal of the next complete cycle starting with the optimal timing is waited for to arrive and the perception signal is received again.

[0176] If the perception signal arrives first and the communication signal arrives before the perception signal is completely received, and the perception signal carries a priority identifier, continue to receive the perception signal, request to resend the communication signal, and receive the retransmitted communication signal;

[0177] When the perception signal arrives first, the communication signal arrives before the perception signal is fully received, and the communication signal carries a priority identifier, the communication signal is received first. After the communication signal is fully received, wait for the next perception signal of a complete cycle starting with the optimal timing to arrive and receive the perception signal again.

[0178] In this embodiment, the periodicity of the perception signal and the priority identifier (also called an identifier, used to indicate that the corresponding signal has a higher priority) provided by the transmitter can be used to determine the priority of the perception signal and the priority of the communication signal. In order to ensure the flexible scheduling of the synaesthesia integration system, it is necessary to ensure that the perception signal can also be received with priority under certain conditions. Figure 7 is a schematic diagram of a method for preferentially receiving a signal with a priority identifier provided by an embodiment. As shown in Figure 7, for a signal that needs to be received with priority (it can be a perception signal or a communication signal), a priority identifier is set in the header of the data packet of the signal before sending to grant priority. The second communication node notifies the first communication node of the form of the priority identifier, and the first communication node preferentially receives the signal with the priority identifier.

[0179] There are several specific situations in which the first communication node (taking UE as an example) preferentially receives a signal with a priority identifier (hereinafter referred to as identifier):

[0180] (1) When both the communication signal and the perception signal have identifiers or do not have identifiers, regardless of whether the communication signal or the perception signal arrives first, the periodicity of the perception signal can be used to determine that the priority of the perception signal is lower than that of the communication signal, and the situation of preferentially receiving the communication signal can be referred to.

[0181] (2) If the communication signal (with identifier) ​​arrives at the UE first and the perception signal arrives at the UE later, the UE continues to receive the communication signal until the reception is complete. Then the UE waits for the next full cycle of the perception signal starting with the optimal timing to arrive and receive it.

[0182] (3) If the perception signal (with an identifier) ​​arrives at the UE first and the communication signal arrives at the UE later, the perception signal will continue to be received. Since the communication signal is sent once, the above operation will cause the communication signal to be lost. Therefore, the UE needs to request the base station to resend the communication signal and then receive the communication signal resent by the base station.

[0183] (4) If the communication signal arrives at the UE first and the perception signal (with an identifier) ​​arrives at the UE later, the reception of the communication signal is interrupted and the perception signal is received first. Since the communication signal is sent once, the above operation causes the communication signal to be lost. Therefore, the UE needs to request the base station to resend the communication signal and then receive the communication signal resent by the base station.

[0184] (5) If the perception signal arrives at the UE first and the communication signal (with identifier) ​​arrives at the UE later, the reception of the perception signal is interrupted and the communication signal is preferentially received until the reception is completed. The UE then waits for the next full cycle of the perception signal starting with the optimal timing to arrive and then receives it again.

[0185] In one embodiment, the priority information includes: priority decision information;

[0186] The method further includes determining priorities of the perception signal and the communication signal according to the priority decision information.

[0187] In this embodiment, priority decision information (which may be in the form of a decision function) may be used to determine the priority of the perception signal and / or the priority of the communication signal. Figure 8 is a schematic diagram of determining signal priority based on a decision function, provided by one embodiment. As shown in Figure 8, for example, some rules may be sent at the transmitting end (the second communication node, such as the base station gNB), and the UE determines a decision function d[n] based on these rules to determine the priority of the communication signal and the perception signal received by the receiving end (the first communication node, such as the UE). When d[n] = 1, the perception signal may be received first; when d[n] = 0, the communication signal may be received first.

[0188] In one embodiment, the priority decision information is determined based on the cycle length of the sensing signal and a preset threshold value;

[0189] In a case where the cycle length of the perception signal is greater than or equal to a preset threshold value, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0190] In a case where the cycle length of the perception signal is less than a preset threshold value, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal.

[0191] In this embodiment, the second communication node may determine priority decision information (decision function) based on the relationship between the cycle length (T) of the sensing signal and a preset threshold value (Th), and notify the first communication node. For example, when T ≥ Th, the time cost of waiting for the next full cycle of the sensing signal is greater than that of retransmitting the communication signal, so the decision function is assigned a value of d[n] = 1, giving priority to receiving the sensing signal. When T < Th, the time cost of retransmitting the communication signal is greater than that of waiting for the next full cycle of the sensing signal, so the decision function is assigned a value of d[n] = 0, giving priority to receiving the communication signal.

[0192] In one embodiment, the priority decision information is determined based on quality indicators of the perception signal and the communication signal;

[0193] In a case where the quality indicator of the perception signal is better than the quality indicator of the communication signal, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0194] In a case where the quality indicator of the communication signal is better than the quality indicator of the perception signal, the priority decision information includes that the priority of the perception signal is lower than the priority of the communication signal.

[0195] In this embodiment, the second communication node may determine the priority decision information (decision function) based on the quality indicators of the perception signal and the communication signal. The quality indicators may include the signal-to-noise ratio (SNR) and / or the transmitted signal power and other indicators that can be used to measure the signal quality.

[0196] When the quality index of the perception signal is better than the quality index of the communication signal, the decision function d[n] = 1, and the perception signal is received first;

[0197] When the quality indicator of the communication signal is better than the quality indicator of the perception signal, the decision function d[n]=0, and the communication signal is received preferentially.

[0198] In one embodiment, the priority decision information is determined according to a cycle length of the sensing signal and a cycle length of the communication signal.

[0199] In this embodiment, by comparing the single cycle length T1 of the perception signal and the single cycle length T2 of the communication signal, the priority decision information (decision function) is determined according to the total time taken to completely receive the two signals, and the priority decision information (decision function) is notified to the first communication node. If the perception signal and the communication signal do not arrive at the receiving end at the same time, the time difference between the two when they first arrive at the receiving end is T r , and satisfies T r<min(T1,T2).

[0200] When the perception signal is received first, the ideal situation is that the retransmitted communication signal does not conflict with the previous communication signal, and the time when the retransmitted communication signal arrives at the receiving end is as close as possible to the time when the perception signal is received.

[0201] When the communication signal is received first, the ideal situation is that when the communication signal is received, the perception signal starts to be received from the next complete cycle.

[0202] In one embodiment, when the sensing signal and the communication signal arrive at the same time,

[0203] In a case where the cycle length of the perception signal is equal to the cycle length of the communication signal, the priority decision information includes whether the priority of the perception signal is higher or lower than the priority of the communication signal;

[0204] In a case where the cycle length of the perception signal is greater than the cycle length of the communication signal, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0205] In a case where the cycle length of the perception signal is shorter than the cycle length of the communication signal, the priority decision information is determined according to the total time taken to receive the perception signal and the total time taken to receive the communication signal.

[0206] In this embodiment, when the perception signal and the communication signal arrive at the same time, the priority decision information is determined according to the cycle length of the perception signal and the cycle length of the communication signal. Figure 9 is a schematic diagram of another method of determining the signal priority according to the decision function provided by an embodiment. As shown in Figure 9, the single cycle length of the perception signal is T1, and the single cycle length of the communication signal is T2. Table 3 shows the minimum time consumption and decision results of preferentially receiving the communication signal and preferentially receiving the perception signal in the three cases of T1=T2, T1>T2, and T1<T2. Among them, when T1<T2, it is defined that T2=nT1, n>1, and represents n rounded up, that is The total time is calculated from the moment a certain signal is first received until the moment another signal is received.

[0207] Table 3 Minimum time consumption and decision results of giving priority to receiving communication signal and giving priority to receiving perception signal under different situations where two signals arrive at the same time

[0208] In one embodiment, when the communication signal arrives first and the sensing signal arrives later,

[0209] In a case where the cycle length of the perception signal is equal to the cycle length of the communication signal, the priority decision information includes whether the priority of the perception signal is higher or lower than the priority of the communication signal;

[0210] In a case where the cycle length of the perception signal is greater than the cycle length of the communication signal, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0211] When the cycle length of the perception signal is less than the cycle length of the communication signal and spans the cycle, the priority decision information is determined according to the total time taken to receive the perception signal and the total time taken to receive the communication signal;

[0212] In a case where the cycle length of the perception signal is shorter than the cycle length of the communication signal and does not span cycles, the priority decision information includes that the priority of the perception signal is lower than the priority of the communication signal.

[0213] In this embodiment, when the communication signal arrives first, the priority decision information is determined based on the cycle length of the perception signal and the cycle length of the communication signal. Figure 10 is a schematic diagram of another method of determining signal priority based on a decision function provided by an embodiment. As shown in Figure 10, the single cycle length of the perception signal is T1, the single cycle length of the communication signal is T2, and the time difference between the first arrival of the two signals is T r Table 4 shows the minimum time consumption and decision results of giving priority to receiving communication signals and perception signals in the three cases of T1=T2, T1>T2, and T1<T2. When T1<T2, define T2=nT1, n>1, and represents n rounded up, that is The total time is calculated from the moment the communication signal is first received until both signals are completely received.

[0214] Table 4 Minimum time consumption and decision results of receiving communication signals and perception signals first in different cases where communication signals arrive first

[0215] In one embodiment, when the sensing signal arrives first and the communication signal arrives later,

[0216] In a case where the cycle length of the perception signal is equal to the cycle length of the communication signal, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0217] In a case where the cycle length of the perception signal is greater than the cycle length of the communication signal and spans the cycle, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0218] In a case where the cycle length of the perception signal is greater than the cycle length of the communication signal and does not span cycles, the priority decision information includes that the priority of the perception signal is higher than the priority of the communication signal;

[0219] In the case that the cycle length of the perception signal is shorter than the cycle length of the communication signal, the priority decision information determines the priority according to the total time consumed to receive the perception signal and the total time consumed to receive the communication signal.

[0220] In this embodiment, when the perception signal arrives first, the priority decision information is determined based on the cycle length of the perception signal and the cycle length of the communication signal. FIG11 is a schematic diagram of another method of determining signal priority based on a decision function provided by an embodiment. As shown in FIG11, the single cycle length of the perception signal is T1, the single cycle length of the communication signal is T2, and the time difference between the first arrival of the two signals is T r Table 5 lists the minimum time consumption of giving priority to receiving communication signals and giving priority to receiving perception signals, as well as the decision results in the three cases of T1=T2, T1>T2, and T1<T2. Among them, when T1<T2, T2=nT1, n>1, and represents n rounded up, that is The total time is calculated from the moment the perception signal is first received until both signals are received.

[0221] Table 5 Minimum time consumption and decision results of receiving communication signals and perception signals first in different cases where the perception signal arrives first

[0222] In one embodiment, the perception signal indication information includes: a cycle length of the perception signal and a cycle length of the communication signal;

[0223] The method further includes:

[0224] Determine the proportion of the time difference between the first arrival of the perception signal and the communication signal in the first arrival signal;

[0225] The priorities of the sensing signal and the communication signal are determined according to the relationship between the proportion and the preset threshold and the periodicity of the sensing signal.

[0226] In this embodiment, the priority of the perception signal and the communication signal is determined by using the periodicity of the perception signal and the ratio of the arrival time difference of the two signals. The ratio of the arrival time difference of the two signals can refer to the ratio of the length of the time difference between the initial arrival of the perception signal and the communication signal to the length of the first arrival signal. Figure 12 is a schematic diagram of another method of determining the signal priority based on the decision function provided by an embodiment. As shown in Figure 12, the second communication node notifies the first communication node of the period length T1 of the perception signal to be sent and the period length T2 of the communication signal. The time difference between the two signals when they first arrive at the first communication node is T r When the second signal arrives, the first communication node calculates T rWhen the proportion of the first type of arriving signals is p, the first communication node comprehensively determines the receiving order based on the relationship between the p value and the preset threshold p0 and the periodicity of the perceived signals.

[0227] In one embodiment, receiving the perception signal and the communication signal according to the perception signal indication information includes:

[0228] In the case where the perception signal and the communication signal arrive at the same time, the communication signal is received, and after the communication signal is received, the perception signal of the next complete cycle starting with the optimal timing is waited for to arrive and the perception signal is received again;

[0229] If the sensing signal arrives first and the communication signal arrives before the sensing signal is completely received, if the proportion is greater than or equal to the preset threshold, the sensing signal will continue to be received, and the communication signal will be requested to be resent, and then the communication signal retransmitted by the base station will be received;

[0230] If the perception signal arrives first and the communication signal arrives before the perception signal is fully received, if the ratio is less than a preset threshold, the reception of the perception signal is interrupted and the communication signal is received first. After the communication signal is fully received, the next full cycle of the perception signal starting with the optimal timing is waited for to arrive and the perception signal is received again.

[0231] When the communication signal arrives first and the perception signal arrives before the communication signal is fully received, the communication signal is received. After the communication signal is fully received, the perception signal of the next complete cycle starting with the optimal timing is waited for to arrive and the perception signal is received again.

[0232] In this embodiment, the proportion of the arrival time difference between the two signals is p, and the preset threshold is p0.

[0233] If the two signals arrive at the same time, the time difference ratio p=0%<p0 must hold true, so the communication signal is received directly, and the perception signal is received again in the next complete cycle.

[0234] If the sensing signal arrives first: the time difference ratio is If p≥p0, the UE continues to receive the sensing signal until it is received, and then receives the retransmitted communication signal. If p<p0, the UE stops receiving the sensing signal, receives the communication signal first, and then receives the sensing signal again in the next full cycle.

[0235] If the communication signal arrives first: the time difference ratio is Regardless of the value of p, the communication signal continues to be received, and then the sensing signal is received again in the next full cycle.

[0236] The priority of the received signal is determined according to the method of any of the above embodiments. If the perception signal is received first, the first communication node can request the base station to retransmit the communication signal in a timely manner, and then receive the communication signal retransmitted by the base station; if the communication signal is received first, the first communication node can utilize the periodic characteristics of the perception signal and directly wait for the next perception signal of a complete cycle starting with the optimal timing to arrive and re-receive it.
